4 Claims.

This invention relates to new and useful improvements in a ventilatorattachment for Windows.

The invention has for an object the construction of a very simple anddurable attachment which may be mounted upon a window and which will becapable of holding a window shade or curtain or other similar element,while in a drawn position, in various spaced positions from 19 1e windowitself. With this arrangement a passage will exist through the windowand around the sides of the shade or curtain, or simiiar element, whichwill serve for ventilation purposes.

15 Still further the invention proposes to characterize the attachmentby a bracket adapted to be mounted upon a window sash or other part of awindow and having a pivot-ally mounted arm and a means for holding saidarm in vari- 20 ous extended positions to engage against a window shadeor curtain or like element to hold it as required.

Still further the invention proposes a novel arrangement andconstruction of the means for 25 holding the shade so that it may beeasily placed into the various positions required.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following description30 and accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

35 Fig. 1 is a perspective view of a window with a ventilator attachmentmounted thereon constructed according to this invention.

Fig. 2 is a fragmentary enlarged plan view of the ventilator attachmentin Fig. 1.

40 Fig. 3 is a fragmentary sectional View taken on the line 3-3 of Fig.2.

Fig. 4 is another fragmentary perspective View of the window sash andventilator attachment.

Fig. 5 is a fragmentary sectional view on the 45 line 5-5 of Fig. 4.

Fig. 6 is a plan View of the device shown in Fig. 5.

The ventilator attachment for windows, according to this invention,includes a bracket 33 50 which is mounted upon a window sash M. Thisbracket 39 has a projecting central portion 3% and side lugs Slb. It isby these side lugs that the bracket is attached on the sash. An arm 32is pivotally mounted on the central portion 30a.

55 This arm consists of a projecting finger 3211 which connects with anarcuate portion 32b engaging against one side of the central portion382a of the bracket. The arcuate portion 3219 continues and connectswith a joining portion 320 which extends over the top of the central 5portion 30a. At the other side it connects with another arcuate portion32d which in turn terminates in an inwardly directed portion 32c coaxialof the arcuate portions 321 and 32d. The inwardly directed portion 326extends into an 10 opening formed in the side of the central portion33a. The arrangement is such that the finger portion 32a may be pivotedupwards and downwards about the portion 326 as a pivot.

The sash 3i constitutes the inner sash of a window construction whichalso has an outer sash 35. The sashes 3i and 35 are slidably supportedin a window frame at and upon the top portion of which the roller of awindow shade 3? is mounted. The arm 32 is adapted to be extendedhorizontally with relation to the sashes or vertically along the sashes,as shown by the dot and dash lines in Fig. 3, by merely pivoting itabout the central portion 33a of the bracket 36.

A block 33 having a serrated front side is mounted on the centralportion 38a and engages against the arcuate portion 32b for resilientlyholding the finger 32a in fixed positions. The arrangement is such thatthe finger 32a may be manually gripped and pulled to disengage thearcuate portion 32b from contacting the serrations of the block 33. Itis then possible to pivot the finger portion 32a upwards and downwardsabout the pivot 326 to various positions. When the finger 32a isreleased the curved por- 35 tion 3211 will re-engage the serrations ofthe block 33.

The operation of the device is as follows: The Window shade 3'! is drawndownwards across the window sashes after one of the sashes has 4 beenopened to permit the air to enter the room. The arm 32 is then pivotedto cause its free end to engage against a portion of the window shade 3?for holding the window shade spaced from the frame 38 to form passagesfor the air at the sides of the shade to permit the room to be betterventilated.

While I have illustrated and described the preferred embodiment of myinvention. it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming Within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

l. A ventilator attachment for windows, comprising a bracket adapted tobe mounted on a window sash, an arm pivotally mounted at one end on saidbracket and having a projecting finger adapted to engage a window shade,or ourtain or the like to hold the same spaced from the window, andmeans for holding said arm extended or parallel with said window,including a serrated element concentric with the pivot of said arm andengaging a portion of said arm, and a resilient: element maintainingsaid arm in contact with said serrated element, comprising a portion ofsaid finger and having sufficient inherent resiliency for engaging saidserrated element.

2. A ventilator attachment for windows, comprising a bracket formounting on a window sash, an arm having one of its ends pivotallysupported upon said bracket and the other of its ends engageable againsta window shade for holding the same spaced from said window, said armcomprising a length of wire consisting of a finger portion having itsouter end engageable against said window shade, an arcuate portioncontinuing from the inner end of said finger portion and engageableagainst one side of said bracket, a joining portion continuing from saidarcuate portion for extending across the faces of said bracket, a secondarcuate portion continuing from said joining portion and engageableagainst the other side of said bracket, and an inwardly directed portioncontinuing from said second arcuate portion and arranged coaxially ofsaid arcuate portions and engageable into an opening formed in theadjacent side of said bracket for pivotally supporting said arm thereon.

3 A ventilator attachment for windows, comprising a bracket for mountingon a window sash, an arm having one of its ends pivotally supported uponsaid bracket and the other of its ends engageable against a window shadefor holding the same spaced from said window, said arm comprising alength of wire consisting of a finger portion having its outer endengageable against said window shade, an arcuate portion continuing fromthe inner end of said finger portion and engageable against one side ofsaid bracket, a joining portion continuing from said arcuate portion forextending across the faces of said bracket, a second arcuate portioncontinuing from said joining portion and engageable against the otherside of said bracket, and an inwardly directed portion continuing fromsaid second arcuate portion and arranged coaxially of said arcuateportions and engageable into an opening formed in the adjacent side ofsaid bracket for pivotally supporting said arm thereon, and means forholding said arm in various pivoted positions on said bracket.

4. A ventilator attachment for windows, comprising a bracket formounting on a window sash, an arm having one of its ends pivotallysupported upon said bracket and the other of its ends engageable againsta window shade for holding the same spaced from said window, said armcomprising a length of wire consisting of a finger portion having itsouter end engageable against said window shade, an arcuate portioncontinuing from the inner end of said finger portion and engageableagainst one side of said bracket, a joining portion continuing from saidarcuate portion for extending across the faces of said bracket, a secondarcuate portion continuing from said joining portion and engageableagainst the other side of said bracket, and an inwardly directed portioncontinuing from said second arcuate portion and arranged coaxially ofsaid arcuate portions and engageable into an opening formed in theadjacent side of said bracket for pivotally supporting said arm thereon,and means for holding said arm in various pivoted positions on saidbracket, said means comprising a block mounted on the side of saidbracket opposed to said opening and having an arcuate side into whichsaid first-mentioned arcuate portion engages, and serrations formed onthe adjacent faces of the arcuate side of said block and saidfirst-mentioned arcuate portion.
